man u ally clutch, in

the

relaininor t as l A v the mil"; he :eh, in may he removwl r om the lever so that hoth hand and toot oi driver are free,

ect of tile invention is the provision of a structure which may he convenently attached i we clutch lever and which calls for sub ally no modification oi the structure or the tractor. llhe hand lever is secured to the stirrup of the clutch lever and a for retaining latch is provided, ld in position by th tool hoe: hells. These "s are utilized, therefore, to accomplish two-told purpose and the structure of the tractor is unchanged.

An object the invention is the provision. of retaining means for holding the clutch in and out, of such character not readily to become detached, even under adverse operating conditions and despite shock and vibration.

it further object of the invention is the provision or"- parts oi especial simplicity and ease of manufacture, capable of hcing turned out at a low cost of production.

lVith the above and other objects in view, which will appear the description proceeds, the invention resides in the novel construction, combination and arrangement of parts substantially as hereinafter de scribed and more particularly defined by the appended claim, it being understood that such changes in the precise embodi- E hi , Serial No. 639,522.

ment of the herein disclosed invention may ,he see 3c of the [the clutch lever is sul stantis ly shaped, having a lat rally directed stirrup l tinreon, terminating in an new "ected flange The hand lc terally directed arm J gainst stirrup ll with which tl made rigid hy rivets ii oted at 17 to the lever, and cured one end to the lever and to the latch urging the latter downwardly. it the upper end ot the hand lover, a hand grip i9 is pivoted, having a link 20 thereon secured at its other end to latch 16. The

latch is provided with a pair of notches oi r ctangular shape, each adapted to cooperate ;h bar 21 which is secured in position he ween tool box 22 and the dash 28, a pair bolts retaining the bar in position, the ordinary bolts provided on the tractor heused for this purpose. The bar 21 projects out from the dash towards the right i'or a considerable distance, and at its end is provided with a slot receiving latch 16. [is hand lever 13 is secured directly to the stirrup and as the tractor is substan tially unmodified tor the reception of bar 21, the tractor is changed but little for the :cception or the novel clutch release lever. (in the movement of the clutch in or out, which is accomplished by means of the foot on the stirrup or by operation of the hand lever, the latch 16 is disposed in such relation to bar 21, that the tension of spring 18 operates when there is no manual pres sure on hand grip 19 to move the latch downwardly, the bar being received in one of the notches therein One out the two notches corresponds therefore, to the in-position oi the clutch, be other to the out position ll he latch is retained snugly in position despite shock and vibration of the tractor, as it is impossible for the latch to move forwardly or rearwardly, as the notch receiving bar 21 is substantially rectangular and has no inclined edge. After the clutch is in proper adjusted position, itis retained therein, it being unnecessary for the toot of the driver to rest on the stirrup. Thus there is absent the fatiguing action of the stirrup heretofore resulting from the prolonged contact of the foot therewith.

Attention is directed to the fact that the locking bar 2st is provided with spaced bolt apertures, whereby it can be conveniently inserted bet'v-icen the tool box and dash, thus utilizing the tool lJOli clamping bolts for attaching the same to the conductor, whereby machine worlc is avoided and economy in assemblage is accomplished, it being understood that the tool box bolts, when tigh ned up, will rigidly clamp the bar 'betvv'een the tool box and dash.

From a practical standpoint this feature important this device is sold as a unit and particularly designed to be applied to a standard tractor by those unskilled in the art cl niecl'ianics.

Another llllPOl'tzil'll) and salient feature in connection with the clutch release mechanism is that the hand love. and associated parts extend ilironi the stirrup and upwardly from the outer end ot the stirrup, whereby the hand lever ii?) forms a strap on the outside of the stirrup, while the clutch lever arm 10 forms an inner strap. Thus this construction will not only eliminate the possibility of the operators loot slipping from its grip upon the stirrup when the de rice -:ncticning, but it also brings tire hand lever outside of the leg of the op erator to a convenient position for gripping and manipulation, whereby the said hand lever can be swung back and forth clear of the operators knee.

1 claim:

In a tractor having a dash, a tool box, bolts for securing the tool box to the dash, the said tractor havin a clutch pedal on one side thereof, terminating with an out wardly extended stirri'ip, the combination oi an :uixiliary clutch lever attachment for controlling the clutch pedal, the same in c uding a bar having an end pressure and s iced bolt apertures adapted to engage the tool boa: bolts, whereby said bar is attached to the tractor between the tool box and dash, a hand lever having an inwardly e1:- tending arm fitted to and secured to the clutch lever stirrup, the hand lever proper forming an outer strap in connection with the clutch lever which forms an inner strap whereby the hand lever is free to travel unoliistructively back and forth outside of the leg or the operator when the mechanism is manually operated, a spring pawl pivoted to the strap portion of the hand lever, the same being fitted through the end aperture ol? the locking bar and notched for engagement therewith, and a hand controlled latch for lifting the pawl.

In testimony that 1 claim the foregoing l. have hereunto set my hand at Milwaukee, in the county of Milwaukee and State of lVisconsin.
